Up to now, though, modern genetic tools have been of limited use for Joshua trees, because no one has assembled the complete DNA sequence of a Joshua tree. Having a “reference genome” would let those of us who study the trees identify specific genes involved in coevolution with yucca moths, compare the evolutionary effects of that pollination mutualism to natural selection exerted by the harsh environments in which the trees grow, and even use genome-scale data to inform Joshua tree conservation planning.

Well, we’ve decided it’s time to do all of that, and we’re asking for help. A team of folks with expertise in Joshua trees’ natural history, Mojave Desert ecology, and genomic data analysis launched the Joshua Tree Genome Project a couple weeks ago, with a crowd-funding campaign on Experiment.com to pay for part of the DNA sequencing we’d need to assemble a reference genome.

We’re approaching 50% of our funding goal, and leading a competition among projects based at undergraduate universities to recruit the most donors, which could win us $2,000 in matching funds — so even if you give as little as $1, you’re providing a big boost to the project. Go check out the Joshua Tree Genome Project website, and then head on over and pledge your support.
